SPECIFICATION forming part of Letters Patent No. 777,096, dated December 13, 1904.

Application filed October 1, 1901.

Serial No. 77,192. (No model.)

To all whom it pea/y concern:

Be it known that 1, REINHOLD HERMAN, a citizen of the United States of America, residing at Grafton, in the county of Allegheny 5 and State of Pennsylvania, have invented certain new and useful Improvements in Printing Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in a printing apparatus, and relates more particularly to that class of machines employed for producing blue solar platinum prints and the like.

The present invention has for its object the provision of novel means whereby prints of the above-described character may be easily produced at night or at any other time by means of artificial light, such as electric light, 2 acetylene-gas light, or the like.

The present invention contemplates to construct a printing apparatus of the above-described character thatwill be mounted upon a portable frame that may be easily conveyed 2 from one portion of the building to another; furthermore, to provide novel means that will allow a gradual descent of the penetrating light to be steadily lowered into the transparent cylinder, and provide novel means whereby the rapidity of the downward movement of the light may be accurately regulated.

The present invention also contemplates to provide an automatic cut-out that will operate when the light or lamp has reached its maximum downward movement.

A still further object of the present invention is to provide a transparent cylinder which may be rotatably mounted in aportable frame and means whereby said cylinder may be 4 locked at different angles or degrees.

A still further object of my invention is to construct a device of the above-described class that will be extremely simple in construction, strong, durable, comparatively inexpensive to manufacture, and highly efficient in its use.

With the above and other objects in view the invention consists in the novel combination and arrangement of parts to be hereinafter I more fully described, and specifically pointed l 5 out in the claims. i

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views, in which- Figure 1 is a side elevation of my improved printing apparatus, partly in section. ig. 2 is a top plan view thereof. Fig. 3 is a vertical sectional view of the transparent cylinder mounted in the portable frame. Fig. 4. is a front and vertical sectional view of the sheave for the lamp. Fig. 5 is an enlarged perspective view of the lower portion of the liquidcylinder, piston, piston-rod, and regulatingvalve. Fig. 6 is a top plan View of a portion of the upper face of the cylinder, showing the pawl and ratchet. Fig. 7 is a longitudinal sectional view of the transparent cylinder and clamps. Fig. 8 is a fragmentary perspective view showing the end of the canvas and manner of attaching the same to the vertical shafts. Fig. 9 is a perspective view of a portion of the vertical shaft mounted on the outer face of the transparent cylinder, showing the fastening means to engage the canvas.

1n the drawings the reference-numeral 1 indicates a portable frame or carriage, being provided with roller-casters 2, this frame 1 being suitably secured together by a brace-rod 3, carrying an extension 4.

The reference-numeral 5 indicates a transparent cylinder which is pivoted centrally at 6 in bearings 7 7, carried by the portable frame. Through one ofsaid bearings extends a shaft 8, carrying on its end a crank-handle 9 and a spring-pressed locking-pin 10, which is adapted to engage in the boss 11, formed integral upon the outer face of the portable frame or carriage 1. A number of said bosses may be arranged upon the frame in order to lock the cylinder at various angles or degrees.

The reference-numeral 152 represents a rotatable frame in which the cylinder is mounted, said frame carrying on its upper and low er extremities a ring 1 1 and 15. Upon said rings are mounted apertured lugs 16, which are adapted to receive the vertically-extending opcrating-shafts 17, these shafts carrying studs 18, one of said shafts being provided with an operating crank-handle 19, to which is fastened the ratchet-wheel 20, operating in conjunction with the locking-pawl 21, pivotally secured upon the ring 14 of the frame.

Canvas or other suitable material is arranged upon the transparent cylinder and passes around the shafts 17, the operating-shaft being secured to the canvas 22 by means of the openings 23 and the studs 18.

The reference numeral 24 represents a standard the base of which is secured to the extension 4 of the portable frame or carriage, the upper end of said standard having secured therein an arm 25, upon the end of which is mounted a sheave 26. A bracket 27 is also secured to the arm and extends outwardly from the other side of the standard 24. In said bracket is mounted a pulley 28. The liquid-cylinder 29 is secured to the extension 4 by means of screw-threads, the upper end of said cylinder being provided with a cap 30, carrying a tubular extension 31.

he reference-numeral 32 indicates the funnel-shaped mouth of the tubular extension 31.

The reference-numeral 33 represents a hollow piston -rod the lower end of which is screw-threaded, as shown at 34, for securing the piston 35, said piston having formed therein ports 36, which are normally closed upon the upward movement of the piston by means of the annular flap-valve 37, which is seated in the valve-seat 38, formed in the piston.

The refereneenumeral 39 represents discharge-ports formed in the hollow piston-rod, these ports arranged in close proximity to the piston.

The reference-numeral 40 represents a regulating-valve arranged in the hollow piston, said valve being attached to the operating rod 41, extending up through the hollow piston, and has formed on its upper end thereof an operating-hai'idle 42.

The reference-1mmeral 43 represents a ring secured to the upper extremity of the hollow piston-rod, said ring carrying an extension 44, to which is attached an operating-cord 45, which passes over the pulley 28 and sheave 26 and carries on its opposite end an electric lamp 46, said lamp having an electrical connection 47, passing over the double pulleys 48 and the sheave 26, said double pulleys having their inner face insulated, carry a brush 50, to the end of the connection 47 and binding-post 51 of the electrical connection 52, said electrical connection 52 having arranged therein a switch 53, secured to the side of the portable frame.

The reference-numeral 54 represents an automatic cut-out, which is operated by a contact 55, carried by an extension 44 of the ring 43. To the latter is also attached an operating-cord 56, which passes over a Windlass 57, operated by the crank-handle 58 of the shaft 59, mounted in the bracket 60, attached rig- I idly to the side of the portable frame. Said shaft 59 also carries a ratchet-wheel 61, which is engaged by the gravity-pawl 62, thereby preventing the reverse rotation of the windlass, as will be readily understood.

The operation of my improved device is as follows: The picture or drawing that is desired to be printed is first placed upon the transparent cylinder and the sheet of paper or other material upon which said picture is to be printed is placed between the paper and canvas. The latter is then drawn taut by means of the operating crank-handle 19 rotatingone of the shafts. By reason of the lamp 6 acting as a counterbalance-weight the piston-rod and piston will be allowed to gradually ascend in the liquid-cylinder, the liquid flowing through the ports 39 of the hollow piston-rod and the downward pressure of the liquid in the cylinder will normally close the flap-valve 37 in the piston as the piston ascends. As the piston-rod and piston gradually ascend I in the cylinder the lamp 46 will be allowed to I gradually and steadily lower itself in the cylinder until the print is completed, when the lamp will have reached the limit of its downward descent, the contact engaging the cutout 54 and will cut out the circuit of the electrical connections leading to thelamp. \Vhen it is desired to return the lamp to its former position, the Windlass 57 is operated by means of the crank-handle 58, thereby lowering the piston and hollow piston-rod, the downward pressure upon the liquid causing to open the flap-valve, which permits a rapid and easy return of the piston and piston-rod to the lowered position in the liquid-cylinder. In order to obtain a more rapid or gradual descent of the lamp, the operating-rod 41 is loweredor raised to either open the ports 39, as shown in the drawings, which will permit a more rapid descent of the lamp than in case the valve 40 is lowered by means of the rod 41 to partially close the ports, which will tend to obstruct the rapid flow of theliquid through the ports, and consequently retard the upward movement of the piston and piston-rod to which the lamp is connected.

The many advantages obtained by the use of my improved apparatus will be readily ap parent from the foregoing description, taken in connection with the accompanying drawings.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what claim as new, and desire to secure by Letters Patent, is-
